So, if you are looking for a Reverse Osmosis countertop system, the RKIN OnliPure Countertop is one of the best choices you can make.

RKIN OnliPure Countertop Reverse Osmosis Filtration Capabilities

Contaminants

The RKIN OnliPure Countertop Reverse Osmosis system’s main focus is to reduce the TDS virtually to zero, removing up to 99% of all water contaminants, such as chlorine, lead, heavy metals, VOCs, fluoride, PFOA, PFOS, and many more.

This rate of contaminant removal is only achieved through a highly effective Reverse Osmosis filtration process combined with other filtration methods. The RKIN OnliPure Reverse Osmosis system contains 4 filtration stages, that work as explained below:

  • Stage #1: a 5-micron sediment filter uses its outer layer to remove larger particles and its inner layer to remove smaller particles, effectively reducing contaminants like sediments, sand, rust, and suspended solids
  • Stage #2: a coconut-based activated carbon block filter uses its adsorption capacity to remove contaminants like VOCs, chemicals, THM’s, disinfection by-products, bad taste & odors, etc.
  • Stage #3: the core of the system, a Reverse Osmosis membrane removes almost to 0 the water TDS (total dissolved solids), removing nasty contaminants like heavy metals, fluoride, nitrates, hormones, bacteria, and many other contaminants
  • Stage #4: finally, a post filter with ion-exchange media gives a final polishing to the water removing any bad odors and impurities from it

Unlike other RO systems, the RKIN OnliPure does not remineralize the water adding back minerals to it, as its focus is removing all particles from the water.

If having more alkaline water is important to you, you can consider a similar product from RKIN, the RKIN AlcaPure Countertop Reverse Osmosis that is basically the same product, the only difference is that on the last filtration stage it has a remineralization filter.
